HelpSpot 3.1.7 Ioncube on FreeBSD 8.2 amd64, Apache 2.2.17, PHP 5.3.6, and MySQL 5.5.12
I have a user (tech) who is getting this message when clicking on the Drafts area when the drafts counter is more than 0 (i.e. a draft is present).
I have confirmed this myself on FIrefox 14.0.1 as well.
This appears to be new behavior since we upgraded to 3.1.7 a few weeks ago.
